RADIATOR.

Specification of Letters Patent,

Patented Nov. 12. 1918'.

Application mea April is, 1917. semi nu. 162.501.

To all whom. 'it may concern:V Be ritlrnown that I, GnoneaH.' Loana, a

citizen of the United States, and a resident of Toledo, in thecount ofLucas Aand State v of Qh10, have invente a. certain new and,`

useful Radiator;and 1 do'hereby declare the following 'tobe a full,clear,4 and exact specification. My inventionrelates to ,'radiators, andit has for' its object to provide an, eilicient radiator 4which may bemade at alow cost.V

The invention provides a [radiator which iis exceedingly .sim le both inits construction and in its assem ling,"and yet provides pas-v .sagewaysfor water-'and for air,V so arranged as to causethe air to pass inintimate contact with .thewalls ofthe radiator throii h which the watercurrent passes' to rapi y cool the water. 'L It also providesA means fordisturbing the'4 air currents and the saine means extends the water`streai-n which Hows between the Wallsofhe radiator.l By m iiiventio'nI'liavealsq-proyidedmeans `w ich allows .for expansion-ofthe water passaf ways when the radiator freezes and for .t e

formsg-of radiator construction. ,For nrposes -miillustrating thepracticabiltyo my ,invention Ihave selected'one'ofsuch conl l of `thewalls 3 `and 4. are provided with angiilar corriigatons. When the walls3 and structiofs. and shallA describe Vit; hereinafter;

' The construction selected, is illustrated inthe 4o IFigure 1 :of thedrawings front view of the radiator. f a side view of oneof the sectionsof the rfavillustrates4 a dieter.

The 4core 2 "may be eonnectcdto water boxes lo# i cated ,inthe upper andiY werpa'rt of thera-v h 'diator Ain the" manner w known inthe 'art V 'had' to -the accompany-ing draw-4 ings, -an 1 to the'characters of reference marked thereon, `which forni a part f` this ipassageways' when 2illustrates honeycomb' appearance found infrailiatois.

toallow the' water to .flow from the upper' Water box through thepassageivaysot'-the radiator to the lower Water box.

The core of the radiator is formed of pairsof Walls 3 and-.t betweenwhich the Water is allowed to pass.` The 'walls' are provided with4siniious recesses which register when 'the radiator plates 3 andpt areplace-1 in im.

vs'ition and thus form passageways S in the radiator.substantially ofcircular cross-.soction. The passageuays are disposed at .shortdistances from each other, leaving1r interim`- diate dat passagewaysconnect-ing the simi'- soidal passagei'i'aj's. A pair ot' springs I and6 are located intermediate eachpair ot' walls Sand l. The springs ."1and 1' .are-'1 also4 siihstantiall)v siliiisoii'lal and extendvertically along` the central` portionv of thi- AWalls 3 and et. Thesprings, 5 andt register att'heir. troughs and at their crests. so thatsprings onopposite sides of the pairs` nl Walls 3 and -flaline to pressthe walls livtween the crests. Likewise the troughs nl the springsoperate to pressagainst each .ot-her, so that` at 'intermediategpointsalong the springgsV they press against the walls 3 .ai-

4 and against each other and'operate to yield; ingly press the-'walls 8and 4 to keep `theiii together.v A- air of plates 7 may he locatedintermediate eacli air of springs and 6. YEach spring will 4tiljiiisbeplaced in a compartment located intermediate the plates 7 and one ortheothe'r of the'walls 3- or el.' :Theedgesgofthepairsof walls Sand-1:nay he 1 corrugated so: las to form; angular -corrugations 9 orcircular. corr'ugation's. In

the '-forniof the invention shown the 'edges wals 3 and 4. Each pair ofwallsmay be.

placed 4side by side so as' to foi-,ni the usual 1n ithe manner wellv'known in the art. lt plates 7 are used and placed between' the 7 are'soplaced wth'respect to the corruga- ..tions of ftheadjoinin .pairsot'y walls as io pairs of walls-their' edges are'likeivise corrugatedyand thecorriigations 10 of tho Vplates by the 3 and 4 and in thepassageways 8. A larger portion of the water passes through thepassageway's on account of the larger cross area of the p assageways.The sinnous form of the passageways carries the water a longerdistanceby .the air currents than if the passageways were straightlthrough the radiator. The air enters the honeycombed radiator front andstrikes the ridges formed in the walls 3 and 4 and thus cools the watercorrugated ridges formed in the wallsB and 4. When the radiator freezesthe Walls 3 and ltwill expand against a yielding pres- Aabut o posing l.sides o the plate,

sure of the springs 5 and 6. When, how-4 ever', the water thaws out, thesprings' 5 and 6 force the walls 3 and 4 togethei` and thus reduoethearea of the passageway for the water between the walls 3 and 4.

`In thepreferred form the springs 5 and 6* are placed on the plate 7 andthe troughs of the springs aresoldered to the plates 7.

The troughs are preferably placed so as to points located on opposite sothat when the plates are placed in position the springs act in oppositedirections to press the walls of the water passageways together, springsalso being placed in alinement press opposing points of the pairs of`walls toward each other.

The invention may be modiiied by those skilled in the art Withoutdeparting from the s irt thereof.l
